Mastering Number Bonds: Exploring Numbers Beyond 10, 100, and 1000

Mastering Number Bonds: Exploring Numbers Beyond 10, 100, and 1000

Learning Objective

At the end of the lesson, you will be able to understand and apply number bonds while crossing boundaries of 10, 100, and 1000.

What do you already know about number bonds and crossing boundaries of 10, 100, and 1000?

What are Number Bonds?

Number bonds are a way of breaking down numbers into their smaller parts or components.

Number Bonds of 10

Number bonds of 10 are pairs of numbers that add up to 10. For example, 7 + 3 = 10.

Crossing the Boundary of 10

When crossing the boundary of 10, you can combine number bonds of 10 to form larger numbers. For example, 7 + 3 = 10, so 70 + 30 = 100.

Number Bonds of 100

Number bonds of 100 are pairs of numbers that add up to 100. For example, 70 + 30 = 100.

Crossing the Boundary of 100

When crossing the boundary of 100, you can combine number bonds of 100 to form larger numbers. For example, 70 + 30 = 100, so 700 + 300 = 1000.

Number Bonds of 1000

Number bonds of 1000 are pairs of numbers that add up to 1000. For example, 700 + 300 = 1000.

Practice Time!

Solve the following number bond equations: 1) ? + 9 = 10, 2) ? + 70 = 100, 3) ? + 700 = 1000.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
